PNEUMATIC STACKER.

SPECIFICATION forming part of Letters Patent No. 633,559, dated September 26, 1899. Application filed February 1, 1896. Renewed November 18, 1898. berial No. 696,826. (No model.)

To a whom it ilta concern.-

Be itknown that I, J OHN B. BARTHOLOMEW, a citizen of the United States, residing at Peoria, in the county of Peoria and State of Illinois, have invented certain new and useful Improvements in Pneumatic Stacker-s; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specificalion.

Figure l is a perspective of a sufficient portion of a thresher and straw-stacking mechanism to illustrate the manner of embodying my improvements. Fig. 2 is a side elevation of the entire machine. Fig. 3 shows,detached, some of the devices for driving the shaft which imparts the reciprocating movement to the stacker. Fig. 4 is a view of another portion of said driving mechanism. Fig. 5 is a side view of the parts which constitute the lock for holding the stacker-tube in operative position. Fig. 6 is a similar view of said look when its parts are in the position occupied at the time the tube is in its inactive position or folded. Fig. 7 is a cross-section of thestackertube and attached parts on the line y y of Fig. 1. Fig. 8 is a sectional view, on an enlarged scale, of the pawl mechanism for regulating the length of the brace. Fig. 9 is a detail perspective view of the supporting devices for the lower end of the brace, the parts being in the positions occupied when the stackertube is in operative position. Fig. 1-0 is a similar view, the parts being in the positions occupied when the stacker-tube is swung forward. Figs. 11 to 13 are detail views of the members or parts of the said support for the lower end of the brace. Fig. 14: is a longitudinal vertical section of the rear end of the separator-casing shown in Figs. 1 and 2. Fig. 15 is a transverse section of the same.

Inasmuch as the matters constituting more particularly the features or improvement herein can be applied to any of the forms of threshing-machines now well known it is unnecessary to describe in detail the parts which constitute the thresher proper, although I havchcrcin (in Fig. 2) illustrated more or less conventionally an entire threshing-machine in order that an understanding can be readily had of the relation thereto of the stacking devices.

A indicates the body part of the thresher, it being supported upon front and rear wheels at a. The cylinder is situated in that part of the thresher indicated by B, and the straw is carried from that end of the machine longitudinally through it to the rear end, the winnowing-fan and the vibrating shoe being arranged in a well-kn own way in that part of the body or casing indicated by O.

The straw,which isfinallydelivered from the separator, is deposited in the receptacle at D at the rear end of the machine, the latter having a sloping bottom (Z, inclined toward one side of the casing.

E represents a fan-casing the eye of which communicates'with the interior of the chamberD. Inside of this fan-casing there is arranged a fan E, which also, as concerns the details of its construction, can be made in any now well-known form.

The straw and chaff chute or guide at D (Z in its relations to the other parts is shown in Figs. 14 and 15. It will be seen that the straw is first deposited in this chute or receptacle D and that it then moves along the bottom thereof, which is inclined downwardly and transversely of the machine, to the ejectorduct for the fan-casing, it, as shown, being on the transverse lines of the eye of the fan and delivering the straw thereto, so that the latter can be carried to the adjustable deliveryduct G above.

Inasmuch as the present invention does not pertain to the details of any particular style of grain-winnower or style of straw-carrier within the separator, it is unnecessary to describe these parts in detail, as they may be of any suitable sort, there being a conventional illustration of such straw-carrier and winnower in Fig. 15. So, too, the rotary movements or horizontal adjustments of the main pneumatic deliveryducts G G G can be efiected by any suitable gearing or other devices such as now well known. A common mechanism for this purpose is more or less conventionally illustrated in the drawings, there being at G a toothed ring or gear-wheel at the lower part of the delivery-duct, driven by gearing supplied with reversing devices, (shown generally at G The delivery-duct leading out from the fan is indicated byF,it extending to a plane at or near the plane of the top or roof of the casing. Upon said roof there is arranged a vibrating support to carry a wind-trunk, which communicates with the aforesaid duct F through an intermediate joint-piece.

In an earlier application, Serial No. 550,986, filed by me on the 28th day of May, 1895, I have shown and described a pneumatic straw-stacking mechanism which as concerns a number of the features of the arrangement and details of construction is more or less similar to that herein and to which reference may be made for a fuller understanding of said details; but my experience with the construction of the earlier sort hasled me to a number of my improvements which I have herein shown and will describe.

G indicates the hood or lower section of the trunk, through which the wind, straw, chaff, &c., are ejected.

G indicates the inner longer duct-section. At the lower end it is so connected to the section G that it can be moved vertically without impairing the substantially air-tight joint with such part G.

G indicates a third or outer duct-section telescopically connected to the section G and adapted to both slide longitudinally thereon and also to be axially rotated more or less. At its outer end it has a segmental head-like portion G which can be either advanced or withdrawn or can be turned around the longitudinal axis of the duct for a purpose to be described.

At the lower end the part G is connected to the vibrating support or framework in substantially the manner described in my said earlier applicatiorn-that is to say, it has yokes orbracket-arms at g, which at their lower ends are provided with rollers g, fitted in guides g having curvilinear slots. In addition to these it is provided with a supporting-yoke ggwhich carries rollers g that engage with the curved guide 9 behind the air-duct and rigidly secured to the vibrating frame.

H is abracing-bar lying below and approximately parallel to the parts G and G At its rear end it is rigidly secured to the frame part above described, preferably near the bracket-strap g, and at a point as far outward as possible it is connected by a bracket or strut h to the tube-section G. At its outer end it is pivotally connected to an inclined brace having the-parts I and 1.

The part I is tubular and adapted to receive the lower part I, the latter being a ratcheted rod which can move longitudinally into the tube, the ratchet-teeth being shown at t.

l I are dogs adapted to engage with the teeth 11. The dog I is pivoted to the vibrating yoke 1 and the dog I is secured by a stationary pivot.

The yoke I carries a lever I by means of which the operator can at any time impart a step-by-step movement longitudinally to the part I of the brace, so as to throw upward the barH and the parts secured thereto. The dogs I and I mutually act to prevent any retraction of the part I when the lever 1 is being moved.

The brace II is at the lower end pivotally connected to the swinging support or hingelike plate J. Said support J is pivoted at-j to a supplemental hinge-plate or swinging carrier J, and the latter is pivoted to the framework of the machine atj.

On examining Fig. Git will be seen that the parts last described can be turned into such position as to permit the brace I I to swing around to the side of the machine and lie in a vertical plane substantially parallel to the machine, this being necessary when the stacker-tube is to be putin its inactive position and lowered for transportation. At such time it rests upon a pillow or supportKnear the front end of the thresher, as shown in Fig. 2.

By examining Fig. 5 it will also be seen that the pivots atjj are so related that the brace I I can be moved around behind the machine, so as to lie in another vertical plane parallel to the longitudinal planes of the machine. To hold it in this latter position, I employ a lock which acts automatically. This is indicated as awhole by L. It is formed of a plate or bar having a hook Z, adapted to engage with a pin or stud Z on the framework. It is also formed with two levers or trip-arms Z Z and is pivoted to the plate J at the point j. The trip-arms Z Z lie in the path of the swinging plate or bar J. When the stackertube is being swung around fromthe inactive position (shown in Fig. 2) to the position of operation, the plates J and J move around the pivots atj and j until finally the plate J bears ICO IIO

againstthe trip-arm Z and compels the hook Z to firmly engage with the pin Z. lVhen the machine is in operation and the stacker-tube is being vibrated from side to side in the ordinary manner, it is stopped by the reversing mechanism at either limit of its movement before the plate J can impinge upon the trip-arms Z Z but when it is desired to fold the parts around in the inactive position again the plate J is carried far enough to strike the triparm Z which automatically releases the hook Z from the pin Z, and thereupon the plates J and J are freed to rotate far enough to allow the brace-rod I I to swing around to the side of the separator. In brief, the brace-rod automatically locks itself in working position and automatically releases itself from the locked position.

The axis of the pivot atj should be on the axial line of the toothed ring or vibrating mechanism at the base of the straw-tube. The sliding section G of the straw-tube is moved or telescoped in relation to the sectio G as follows:

M is a ring or band extending partly or entirely around the sliding section G M is a block or rope attachment loosely engaging with the ring or band M. They may be loosely joined by having a flange m formed on or secured to the ring and having engaging lips or flanges m on the block or attachment M.

N is a rope or cable extending from a sheave n on the bar H to the sheaves a near the outer end of the bar. The ends of the cable are connected to the ends of a chain 0, which extends downward to and around and engages with a sprocket O, mounted in a bracket 0, secured to the brace-barI and hav ing a crank 0 The chain and rope or cabletogether constitute an endless flexible device. One side or strand of the cable is secured to the above'described block or attachment-piece M. It will be seen that if the crank 0 be turned in one direction the draft will be exerted on the sliding tube-section in such way as to cause it to move out on the tube-section G and that if the crankis turned oppositely said tube-section will be drawn in. In this way the total length of the air and straw duet can be readily adjusted.

The end piece or head G of the duct being integral or solid with the telescoping part G I provide for rotating both these parts G and G in order to guide or deflect the straw to the right or the left horizontally.

P P indicate one or more ropes. The part P is secured to the top of the aforesaid band or ring M and extends down on the righthand side of the straw-tube. The part P extends down from the top of the ring on the left-hand side of the tube. The lower ends of the rope or ropes are temporarily supported in any suitable manner. hen it is desired to direct the escaping straw toward the right, a pull is exerted upon the left-hand rope P, which rocks or turns the telescoping part G of the tube in the proper manner to effect this. \Vhen it is desired to turn the straw to the left, downward draft is exerted upon the other rope P.

It is sometimes desirable to throw the oscillating mechanism which vibrates the duct out of action even when the vibrator and separator continue in motion.

Q is the drive-chain, which brings power from a suitable sprocket to the sprocket R on the shaft R at the rear of the machine. This shaft is also providedwith a sprocket T, a clutch S, and a crank R The power-re ceiving wheel R is loose on the shaft.

U is a chain extending from the sprocket T to the sprocket-wheel V. The latter rotates a pinion V, which engages with a spurwheel \V on the shaft I the latter being connected to the gearing forming the principal part of the oscillating devices. These devices may be substantially similar to those in my aforesaid earlier application and need not be here described in detail.

IVhenever it is desired to disengage the stacker mechanism from the thresher and separator, it can be readily done by moving the lever S, which throws the clutch S out of engagement with the wheel R. W'hile so held out the operator by hand can actuate the crank R in such way as to swing the strawtube to the right or the left, as desired, and

to whatever extent is wished.

It will be seen that with the stacking mechanism illustrated and above described but a single operator is required at the rear end of the machine and that he can accomplish all of the necessary adjustments and manipulations while standing upon the ground,whether it be the elongating or shortening of the strawduct by the crank O or the elevating or lowering of the tube by the lever 1 or the guiding to the right or to the left of the escaping straw by the ropes P P or the throwing out ofaction of the oscillator by the clutch S and the turning of the duct to one side or the other by the crank R Thus I avoid the neessity of having an operator upon the top of the machine or in an elevated position, as has been required with many of the earlier styles of construction.

It will be seen that the duct of trunk is supported by devices of the nature of a crane, the important members of which are below the trunk, these being a bar or bars supplemental to the trunk and stationary relatively to the inner section thereof, although vibratable and adjustable therewith, and a downward and inclined brace, which is also stationary with respect to the inner section of the trunk, but vibratable therewith, it con stituting the extension member of the support.

A pneumatic stacker having the features of construction which 1 have herein presented is superior to others with which I am acquainted, not only in giving the strong and effective vertical support due to this under brace or bar, but also because I can remove from above the trunk all of the upwardlyprojecting parts employed in earlier constructions which have prevented the machine from being taken into barns or other places where obstructions were present. Vhen the trunk isin the horizontal position,

too

the downward force at the outer end is at its 7 maximum, and this decreases as the trunk is carried toward the vertical. Vith an under brace of the sort herein shown the parts can be so arranged, withoutincreasingt'he height of the entire mechanism, that the angle of the brace at its outer end shall be such that it can easily take the entire downward thrust in whatsoever position the trunk maybe adjusted vertically.

I am aware of the fact thatbraces have been employed in connection with the frames of endless belts used for various purposes, including thecarrying of straw; but I believe myself to be the first to have devised apneumatic stacker and an under brace therefor.- to wit, a brace extending downward and backward from a point relatively near the outer end of the inner trunk-section-and both so arranged that they can be readily applied to the rear end of a thresher in such way as to dispense with the numerous parts and complicated mechanisms and the supplemental supporting devices which have been heretofore required when brace-supported endless-belt stackers were used.
